Abstract
A method of finishing a barrier fabric includes applying a non-aqueous solution of low surface tension solvent and fluorochemical repellent to a barrier fabric, subjecting the barrier fabric to conditions sufficient to remove the solvent from the barrier fabric, and applying an aqueous-based antistat to a surface of the barrier fabric. The low surface tension solvent substantially covers all fibers in the barrier fabric with the fluorochemical repellent. The antistat is prevented by the fluorochemical from migrating from the surface to which it is applied.
